Hi SONSIVRI Team. In advance I really appreciate your big effort for providing great resources in all aspects of especially electrical & Computer engineering. I was acquired with this forum about 3 years ago and since then I have been using it for my projects. By the way I forgot to introduce myself. I am graduating in electrical engineering (MS degree). My Specialty is providing digital hardware for communication baseband. I have been using EDAs from famous companies i.e. Synopsys & Cadence & Mentor Graphics specially in designing & verification of hard IPs. My MS thesis was "Hardware Implementation of SDR based low power Turbo codes for 4G generation and its true implementation on Virtex 5 FPGA".I love digital and EDAs and someday I want to be a verification engineer & SOC designer . I think working as a team on this forum raise my knowledge and pay the way in reaching my goals.By the way I think we can be stronger than "bbs.eetop.cn" with working hard and sharing everything that we find valuable.At my first post I will send Mentor Graphics Modelsim& Questa 10 patch file and will tell how to fix Agilent ADS 2011.1 patch problem. I am working on Aldec Riviera 2011.2 and Alint 2010.10 SR1 and will send appropriate cracks. Thanks a lot for reading this notes.
